This work represents the first pharmacological analysis on the crude hydroalcoholic extract of Palythoa caribaeorum. The analgesic activity was assayed in acetic acid-induced writhing test and with the hot-plate test with mice; while the anti-inflammatory activity was evaluated in carrageenan-induced hind paw edema in the rat. The analysis suggested an analgesic activity in the Writhing test on the group treated with the crude extract (200 mg.kg-1 v.o.) with an abdominal contortions inhibition of 47,22 %.
